The reason why is oil pan is dripping is not because the thread on his pain is stripped but because he broke his oil pan nut. This is always 99.9% of the problem. Rarely do the pan thread strip because the force that is require to strip the tread will cause the bolt to break first.

The nut is hollow and when it breaks oil will drip out of it.

All he has to do is remove or completely break his oil drain nut and remove it with an Allen key.

People like u and most mechanics will always assume the worst and end up fixing the problem the hard and expensive way.
